The linear first-order differential equation governing the current in this circuit is given by the following. LI' + RI = E(t) Suppose that L = 5 H, R = 202, and the source E of emf is an alternating-current generator that supplies a voltage of E(t) = 100 cos (40t) V. Suppose that the switch is initially in position 2, but is thrown to position 1 at time t = 0 so that I(0) = 0. Determine the subsequent inductor current, I(t). E Switch 2 R wwarrow_forward
